Case Study

L1 blockchain with built‑in perpetual DEX (end‑to‑end)

Performance‑oriented Layer‑1 on Rust with deterministic EVM, native token economics, on‑chain perpetual orderbook, privacy layer (Bulletproofs), and a full product suite: DEX UI, Explorer, Operator Panel, Faucet, SDK.

25+Rust core modules
4Frontend apps shipped
90+API endpoints
Year: 2025Industry: Blockchain / DeFiTimeline: 4 months

Problem

Trading latency and cost on general‑purpose L1s force perpetual DEX projects into off‑chain compromises that sacrifice verifiability. The partner needed a purpose‑built chain where the matching engine, margin logic, and settlement live at the protocol level — with full EVM compatibility, a native token with hard‑capped economics, and governance that limits parameter changes to safe bounds.

Constraints

  • •Deterministic execution: same input → same result (critical for batch replay and fraud proofs)
  • •EVM compatibility: MetaMask, ethers, Hardhat, Solidity contracts must work natively
  • •Native token accessible from EVM without ERC‑20 wrapper (precompile 0x0a)
  • •Perpetual DEX logic at protocol level, not in smart contracts
  • •Privacy layer: shielded orders with cryptographic range proofs (Bulletproofs)
  • •Governance bounded by hard‑coded limits — no arbitrary parameter overrides
  • •Full product suite: DEX terminal, block explorer, operator panel, faucet, SDK
  • •Detailed data under NDA — portfolio shows architecture and capabilities

Solution

Built a single‑binary Rust node (25+ core modules) integrating consensus, validator registry, governance, slashing, fee market, EVM executor (revm, EIP‑1559/2930 + BN256 pairing precompiles EIP‑196/197 for full Ethereum precompile compatibility), native token state, DEX engine (orderbook, positions, trades, OHLC candles), privacy primitives (Bulletproofs), checkpoint sync, and hybrid storage. The node exposes 90+ HTTP endpoints, JSON‑RPC (Ethereum‑compatible), and WebSocket (EVM subscriptions + DEX realtime streams). Shipped four Next.js applications: DEX trading terminal, public block explorer with contract verification, operator UI for node management/governance/staking, and testnet faucet. Two TypeScript SDKs: @armadex/sdk (explorer/contracts) + DEX SDK (trading integration).

Deliverables

  • L1 node on Rust: 25+ core modules, consensus, validators, governance, slashing, fee market, sync (62 integration test suites)
  • Deterministic EVM executor (revm) with EIP‑1559/2930 and native token precompile
  • On‑chain perpetual DEX: orderbook, matching, positions, trades, OHLC, WebSocket streams
  • Privacy layer with Bulletproofs for shielded orders
  • Token economics: hard‑capped supply, epoch‑based emission, staking rewards
  • DEX Trading UI (Next.js): terminal, charts, order forms, wallet integration
  • Block Explorer: batches, transactions, contract verification, statistics, gas tracker
  • Operator Panel: node status, governance, staking, fraud proof, sync, rolling updates
  • Testnet Faucet with MetaMask integration
  • 2 TypeScript SDKs: @armadex/sdk (explorer/contracts) + DEX SDK (trading integration)
  • Solidity contracts + Hardhat deployment scripts
  • CI/CD, Prometheus/Grafana, OpenTelemetry, Nginx rate limiting (77 automation scripts, 28 documentation files)

Outcome

Testnet Alpha deployed and running: 7 active validators, 1.6M+ finalized batches (as of testnet alpha), 99%+ success rate. Full product suite operational across 90+ API endpoints: DEX terminal with realtime orderbook, block explorer with contract verification and gas tracker, operator panel with governance/staking/fraud proof controls, working faucet. Batches processed every ~2 seconds with sub‑250ms commit latency. 62 integration test suites, 77 automation scripts, 28 documentation files. Architecture, test coverage, and operational tooling at production‑grade level.

Hard parts we solved

Deterministic EVM with native token bridge

EVM execution must be fully deterministic for batch replay and fraud proofs. We run revm with EIP‑1559/2930 support, BN256 pairing precompiles (EIP‑196/197) for full Ethereum precompile compatibility, and expose the native token via a custom precompile at address 0x0a (balanceOf, transfer, totalSupply) — no ERC‑20 wrapper duplication. Every state transition is reproducible across nodes.

Protocol‑level perpetual DEX engine

Orderbook, matching, positions, margin calculations, and trade settlement live inside the node binary, finalized by the same consensus as regular transactions. WebSocket streams deliver realtime updates to the UI. Shielded orders use Bulletproofs for cryptographic range proofs.

Governance within hard bounds

Protocol parameters can be changed through on‑chain proposals, but only within pre‑defined bounds hard‑coded into the node. Prevents governance attacks while preserving flexibility. Quorum 33%, regular >50%, critical >67%. Slashing is irreversible — governance cannot rollback penalties.

Four production‑grade frontends

DEX Trading UI with realtime charts, orderbook depth, and wallet connection. ArmaScan explorer with contract verification via solc, gas tracker with cost calculator, and data export. Operator Panel for node monitoring, governance, staking, fraud proof, sync, and rolling updates. Faucet with MetaMask auto‑fill and rate limiting.
